Equipment that exactly examines the rising warmth dissipation drawback in smaller semiconductors has been domestically developed. This marks the world’s second commercialization after the United States and the one one in Korea. The researcher who led the event acquired a commendation from the Minister of Science and ICT (MSIT).
Daegu Gyeongbuk Institute of Science and Technology (DGIST) introduced that Principal Researcher Lee Hyun-joon of the Semiconductor-AX Research Group acquired a ministerial commendation from the MSIT at ‘World IT Show (WIS) 2026,’ Korea’s largest Information and Communications Technology (ICT) exhibition, in recognition of his contributions to know-how commercialization.
As semiconductor gadgets improve in data processing pace and circuit density, they generate extra warmth. Accurately figuring out the place and the way a lot they warmth up is essential for enhancing design and stopping malfunctions. Conventional infrared cameras battle to exactly pinpoint hot spots in semiconductor circuits smaller than a micrometer (μm, one-millionth of a meter).
The analysis crew opted for a way utilizing seen gentle as an alternative of infrared. As temperature rises, the diploma to which gentle displays off an object’s floor modifications minutely. This is the ‘thermoreflectance’ technique, which measures temperature by studying these modifications in reflectivity. It can detect warmth in microscopic spots which can be invisible to infrared cameras.
Building on preliminary know-how from the Korea Basic Science Institute (KBSI), DGIST collaborated with Nanoscope Systems, an organization specializing in optical evaluation gear, for about 10 years to advance the know-how. They succeeded in creating gear that may visualize the placement of micro-heating and the method of warmth propagation inside a semiconductor in real-time.

The analysis crew is at the moment conducting follow-up analysis to combine synthetic intelligence (AI) with the present know-how to exactly detect faint thermal alerts that had been beforehand troublesome to determine.
“We have secured a technology that allows for the direct observation of micro-heating inside semiconductors, which was previously impossible to verify,” mentioned Principal Researcher Lee Hyun-joon. “This presents a new analytical tool that can be widely used in research on next-generation advanced devices.”
